Hibernate Environment in JBoss

Hi,
I have two same copy of JBoss and same classpath entries and corresponding jars in the classpath which are resided in the same folder hierarchy on two servers.When I am starting up JBoss in one server it is showing
[Environment] Hibernate 3.3.1.GA
[Environment] hibernate.properties not found
[Environment] Bytecode provider name : javassist

Where to find out which hibernate and byte code provider is being used.This query is linked with my previous query I think this is the reason.Again I repeat both JBoss copies and jar files in the classpaths and .bash_profile copies are same.Is there anything that depends on the system ? Thanks in advance.
